Teck Resources Ltd is currently running 34.0% annualised volatility over the last 21 sessions. Measured against TECK's own 13 years of daily returns rather than a market-wide average, that is the 19th percentile — unusually subdued by its own history, against a typical reading of 45.2%. The distinction matters because a number that looks calm for one stock is turbulent for another, and the absolute figure on its own tells you neither.

TECK is trading -10.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -40.3%, and the deepest was -80.6% in 2015. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits +8.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 58th percentile — a somewhat wider gap than its own norm. Over the past year TECK closed higher on 51% of sessions, and it is currently 2 sessions into a falling streak.

On October specifically: over 14 years of records, TECK finished the month higher 4 of 14 times, with a median return of -4.0% and an average of -1.1%. Its strongest month historically has been April at +7.8% on average, its weakest March at -2.0%. Seasonality is a weak signal on its own — a decade is a small sample and regimes change — but it is a real distribution rather than a rule of thumb.

Overnight risk is measurable too: TECK has opened more than 2% away from the prior close in 451 of 3,268 sessions (13.8% of the time), with the largest gaps running +16.1% and -11.5%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against TECK's own 13-year history, not a peer group or index.
